public class ServerSideException
extends java.lang.RuntimeException
implements java.io.Serializable, java.io.Externalizable, SecureExternalizable

A wrapper for server-side exceptions that avoids direct references to classes or other exceptions.

This class addresses the issue of potential class loading or serialization problems when transmitting exceptions across network boundaries. Instead of directly referencing classes or exceptions in the cause chain, it decomposes the causes into individual strings and reconstructs them on the receiving end using a dedicated wrapper class. This ensures that the exception information can be safely transmitted and reconstructed without encountering class definition conflicts or inconsistencies.
